MEXICO CITY  Mexican federal police fired on a U.S. Embassy vehicle and wounded two U.S. government employees Friday after their vehicle drove into a rural, mountainous area outside the capital where the officers were looking for criminals, Mexican and U.S. officials said

A US embassy statement said the diplomatic car was "ambushed by a group of individuals." But it added that the Mexican government also admitted that federal police shot at the vehicle and detained officers who were involved.
